IMPROVEMENT. IN, FEED-STEAMERS.

' Specification forming part ofV Letters Patent,No.`205,4ll)9A, dated June 25,1878 application filed Y June2,1877.":r5 .g

To all whom it may concern: v

Be it known that we, WM. M. PARICaRand WILFORD W. YoKoM, of Parkersburg, in the county of jButler and State of Iowa, have invented a new and useful ImprovementA in Feed-Steamers; and We do hereby delare that the following is a full 'and exact description of the same, reference fbeing had to the Aacd companying drawings and to the letterslof reference marked thereon. 5

This invention, which we term the! Hawkeye FeedSteamer,77 relates to that class of boilers which are employed for steaming food for stock; and it consists, mainly, first, in the combination, with the permanent fines, of aremovable lining-pipe and, second, inf the combination, with permanent flues and removable lining-pipes, of certain removable caps.

It consists, further, in certain details of construction, which, in connection with the foregoing, will be fully described hereinafter.

On the drawings, Figure l represents a central longitudinal sectionalV elevation of our invention Fig. 2, a front elevation of the same;

Fig. 3, a rear end elevation of the fire-box,

Fig. 4, a front end elevation of the fire-box Fig. 5, a front elevation of the boiler with theV cap removed; Fig. 6, a centralv longitudinal sectional elevation of the same; and Fig. 7, an elevation, partially in section, ofthe flueB and the interior lining-pipe b.

To enable others'skilled in the art to make and use our invention, we will now proceed to describe fully its construction and manner of operation.

A represents the cylindrical body or shell of the boiler, constructed of any proper size and suitable material, but preferably of heavy t a a represent the boiler,- heads, constructed generally-in any proper manner, but preferably stamped from a plate of extra heavy galvanized iron.

al, Fig. 6, represents a lian ge of proper width, projecting from the circumference of the heads, and a2 an oval recess formed in the lower part of the same by depressing that portion the plate, as shown. a3 a3 represent holes of any proper size and number, which are formed'in the depressed portion of the plate; and a4 a4, flanges of proper width surrounding the holes, as shown.

i The heads of thevboiler are united to the shell'` by driving them tightly inplace, and then riveting and soldering them to make a erfect 'oint. 1 a5 a5 re resent water-@ages of p J p e :a

any` proper description, and a a draw oft cock, by means of which. the contents of ythe boiler may be entirely discharged whendesired. f

, a7, Fig. l, represents a proper pipe or opening, by means of which the boilermay belsupplied with water, and `which may be so arranged, also, as toserve as a safety-valve; and a", a discharge-pipe, through which the steam formed therein may be conveyed away to any desired point.

B, Figs. l and 7, represents the pipes or lues, of any proper diameter and length, formed preferably of heavy galvanized iron, which are driven to their places inthe heads in the usual manner, and are then riveted and soldered to the anges around the openings in anyA proper manner. 1 f

b, Figs. l and 7 represents an internal pipe of sheet-iron, which forms a lining for the ue proper, and protects the same from the direct action of the heat. y

C, Figs. l and 2, represents the body of the tire-box, consisting preferably of a heavy piece of boiler-iron bent into semi-cylindrical or serni-oval form, as shown.

c, Figs. 2 and 4, represents the front-end section of the fire-box, consisting of acasting or plate c1 of semicircular or semioval form, to

correspond with the iireboX in crosssection, which is provided with'fsthe.supporting-legs c2 c2, the opening c3 for thedoor, the inwardly-- projecting flange c4, Fig.` 4f", adapted to receive and support the boiler, as shown, and the inwardly-projecting flange c5, adapted to receive and support the shell of the fire-box.

c6 c6, Figs. 2 and 4, represent proper bolts in the arms cFI c7, by means of which the boiler is securely fastened to the casting when all the parts are in place. o8 represents an ear or lug,

and c9 a rivet or bolt, by means of which the shell. of the lire-box is securely united to the casting. 01 represents the fire-door, and c the hearth-plate.

D represents the rear-end section of the fireboX, consisting of a cast plate, similar to the frontend section, but provided with an Open PATENT OFFICE.

ing and 11u@ meteor F4box d, Rhr means of which the heat and products of combustion are discharged from theiiire-box, as shown'in Fig. 1. v

E, Figs. 1 and 2, represents a plate, preferably of sheet-iron, which is placed underneath kthe boiler, as shown,for the purpose of protecting the same from the direct action of the heat. This plate is bent at its edges, so as to hook over the iire-box, as shown in cross-section in Fig. 2. 4

F represents the grate, of any proper construction. G, Fig. 1, represents a cap, con! sisting of an oval plate, e, having a lange, el, adapted to project into the oval recess of the boiler-head, as shown. e2 represents a flue or pipe, by means of which connection is made with the ue-bofx d of the end section D, as shown. y

H, Figs. 1 and 2, representsa similar cap, Vadapted to iit the oval recess at the frontend of the boiler, which is provided with a pipe oriiu'e, h, adapted to convey away the products of combustion to any proper point of discharge. The operationvolf our improved apparatus will be readily understood. Fire having been made in the rire-box, the products of combustion pass through the flue-box, rear cap-chainber, and ues to the front cap-chamber and smokepipe, as indicated by the arrows, Fig. 1, bywhich means the water in the boiler is heated and steam generated, for the purpose described. From the boiler the steam is conveyed through a rubber tube or other proper pipe to the vat, trough, or other receptacle containing the food to be steamed.

`Some of Athe advantages of this construction are as follows: The fire-box being made in sections, different materials can be used in its construction, and it can be readily put together for use. By means of the interposed shield or plate the boiler is protected from the direct action of the heat. IV hen this plate has been injured by long use, it may be easily removed to permit the introduction of a new one by removing the bolts which fasten the boiler to the end sections. The oval caps may be readily removed when desired, so that the lining of the iiues may be removed for the introduction of new pipes when desired.

The construction as a whole is simple,'yet well adapted for the purpose described.

If desired, two or more discharge-pipes for drawing oii the steam may be used.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a boiler having permanent flues and a removable-lining pipe, a removable cap, substantially as described, adapted to permit access to the flues.

2. In combination with a boiler having permanent ilues and removable lining pipes, the caps G H, adapted to permit access at each end, as described, for the purpose set forth.

3. In combination with the {ire-box D, having thc fluebox d, the removable cap G, having the ue e2, as described.

4. In combination with the semi-cylindrical body C and the interposed plate E, the independent ends c d, as described.

This specification signed and witnessed this 4th day of May, 1877.
